Overview
The 2008 Blue Bird Vision instrument cluster is a single unit containing all electronic
guages manufactured by Stoneridge®. In addition to gauges, the instrument panel
includes a centrally located LCD panel called the Driver Information Display (DID), an
array of driver alert lights, and audible signals. The instrument cluster is not designed
for disassembly. If faulty, it is replaced as a unit.
Because all of the gauges are electronic, there are no mechanically driven linkages such as speedometer or tachometer cables. The cluster receives both analog
inputs from such components as the fuel tank sender and instrument panel dimmer
switch; and digital inputs from components such as the engine and transmission
control modules, via the J1939 databus and hard wire. Depending upon its current
mode, the DID panel can display both driver-oriented information (such as fuel mileage statistics) or service-oriented information (such as engine, transmission, and ABS
fault codes). The buttons on the right steering column stalk are used to cycle the DID
through its various modes and menus.
Although the instrument cluster is electronic, it is not part of the Vision’s Multiplex system. Instruments or warning lights in the cluster may receive signals which
are output from the Multiplex system (such as those for turn signal indicators), but
they are not part of the Multiplex system’s programming logic.
On Visions equipped with hydraulic brakes, the instrument cluster contains 6
gauges. Buses equipped with air brakes have two additional gauges indicating primary (rear) and secondary (front) air pressure.

The instrument cluster is programmed at the factory according to certain features
purchased with the specific bus. For example, the cluster on a bus equipped with
air brakes is programmed to display applied brake pressure, whereas the cluster on
a bus with hydraulic brakes is not. At the time of this writing, sixteen different configurations of the instrument cluster are installed on Blue Bird Visions. Each different configuration is assigned its own part number. When ordering a replacement
instrument cluster, refer to the bus’s Service Parts List (supplied with the bus) for the
specific part number.

7. DRIVER INFORMATION DISPLAY (DID)
The DID is intended to provide information to the driver in a graphical way. The DID is capable of displaying
gauges, telltales and messages. The DID has several modes that depend on the current status of the vehicle
(i.e. driving or not driving). While in driving mode, the DID should always show gauge information if there is no
user interaction. Three different modes have been defined in order to simplify the understanding of the possible
states that the DID supports. Such modes are:
x
x
x
Default Driving Mode (DDM): This is the default view of the display, regardless of the state of the
vehicle (i.e. moving or not moving). The cluster will always return to this view after a period of no
activity, in the Stalk user interface. The allowed time without activity will depend on whether the bus is
moving (speed > 1 MPH) or not (speed < 1 MPH) when a Stalk switch was pressed, while in the
interactive driving mode. In the first case the timeout will be 7 seconds in the second case the timeout
will be 15 seconds. Table 5 describes this conditioning in detail.
Timeout values are handled through EEPROM parameters: EE_DRIVING_M_TIMEOUT,
EE_NON_DRIVING_M_TIMEOUT.
Interactive Driving Mode (IDM): This mode is accessed when the user presses the select key, while in
the default view (DDM). Additional information can be accessed during this mode.
Non Driving Mode (NDM): Accessed when a rollover of the menu is performed and the vehicle is not
moving. Access to diagnostics and data log can be accessed in this mode.

Table 5: Stalk inactivity timeout
Allowed inactivity period is determined every time the stalk switches are operated and is not changed when the
bus speed changes. For example if vehicle was stopped, and the select button is pressed the timeout is started
(15 seconds) then the vehicle starts moving (speed > 1MPH) the timeout value will remain as 15 seconds.
Using the password option it is possible to disable the timeout that returns from any screen to the Default
Driving Mode (DDM) after the interval of inactivity has expired. This action allows the user to work with the unit
in a debug mode, where the timeout is not returning to the default driving menu after 15 seconds of inactivity.
Details about password protected functionality are provided in following sections.

Esc (escape) is used to return to the pervious menu and cancel a setting operation
<ŋ Select is used to activate the highlighted option in the menu. Also it is used as the “enter” key.
Up arrow moves the cursor up, also increments a numeric value during setting operations.
Down arrow moves the cursor down, also decrements a numeric value during setting operations.
7.1.1. Driving Mode window
This area is always present regardless of vehicle speed.
7.1.2. Clock window
This area displays current time information in the format selected via “Display settings” menu.
7.1.3. Odometer window
The odometer displays 0.0 to 9,999,999.9 km or miles that correspond to total vehicle distance value. The
resolution is 0.1 miles or 0.1 km depending on the current unit selection.
If the maximum value that can be displayed is exceeded the cluster will continue accumulating distance but the
most significant digit will be invisible to the driver.
Odometer value is calculated using vehicle speed received via J1939 Cruise Control/Vehicle Speed message
from the ECM PGN 65265 (0xFEF1), SPN Wheel-based Vehicle Speed.
Calculated value will be stored in the non-volatile memory every half a mile (0.5 mile) and when ignition OFF is
detected.
It can be displayed in miles or kilometers as selected via “Display settings” menu.
652
The odometer information must be transferable to a new gauge package in situations when a gauge package
fails. The parameter to use is EE_COV. The EE_COV value is a 32 bit unsigned value with resolution 0.01
miles/bit added to the odometer value. EE_COV value can be updated using Volvo Workshop tool.
It is recommended to reset the trip odometer after EE_COV parameter is updated since the trip odometer value
may result in an inaccurate value.
The odometer shall be readable with the ignition off when the vehicle back lighting (headlight switch in park light
position) is activated.
The cluster should be able to accurately save/retrieve the odometer value for a minimum of 1,000,000 miles.
7.1.4. Favorite Display window
This window will display the first gauge of the “Default Driving Mode” screen. For the 8 gauges version this
window will always display the reading corresponding to air application. For the 6 gauges version it might
contain any of the gauges available in the display: air suspension, transmission temperature or ammeter.
In the Interactive driving mode (IDM) the same gauge information is displayed.
In the non-driving mode (NDM) this window becomes part of menu window.

7.1.6. Information, warning and alarm indicators
DID will display 3 types of indicators: information, warnings and alarms. When specific conditions are detected
a window displaying an icon that represents the condition will popup.
Information, warning and alarm indicators can be acknowledged by pressing the ESC button. Once an
information or warning message is acknowledged it will not be displayed again until the associated condition
becomes inactive and then active again. Alarm indicators will popup cyclically (every 10 seconds) since they
can not be inhibited. Alarms are associated to high-risk conditions, and hence they will keep alerting the user,
as the condition exists.
The info/warning/alarm works slightly different depending on current operation mode, these differences are
described below.
More than one indicator can be active at the same time. A displayed message can be replaced by a new
message provided the new message has a higher priority.

7.3.2. Diagnostics
The DID shall provide monitoring capabilities. They can be divided in two different needs:
x Monitor all digital and analog inputs in real-time: The intent is to provide a way to easily diagnose all
digital and analog inputs connected to the cluster. This is done, providing a reading of the current state
of all digital and analog inputs as is described in detail in A/D Input Diagnostics.
x Fault Diagnostics: The purpose of this feature is to provide a way to monitor data trouble codes
(DTCs) generated by the ECUs in the vehicle: Engine, Automatic Transmission, Hydraulic ABS System
and Air Brake System. Details of these functions are provided in the next paragraphs.
661
7.3.2.1. Fault Diagnostics
Vision Cluster is connected to J1939 and J1708 networks of the vehicle. Not all the ECUs will report their Data
Trouble Codes (DTC) in both networks. Table 8 indicates the network used by each ECU to report its faults.
Only active faults will be displayed.

7.3.2.4. A/D Input Diagnostics
The cluster should provide means for reading the current state of all digital and analog inputs at a given time.
Outputs will not be monitored. The cluster will use the DID to provide such information to the user. The DID will
reflect any change of the status of the input no later than 1 second after a state transition occurred.
Under this option it will be possible to select between digital or analog inputs. Once selected the type of inputs
to monitor, a set of 5 inputs with their current status will be displayed. The name of the input that will be used is
provided in Table 10 and Table 11 in the Caption column; input value will be displayed as described in the
Readout column. As an example, the first screen of the digital inputs will display as depicted in Table 9.

Table 9: First Screen of Digital Inputs
More than one screen will be needed to display all inputs available in the cluster. Navigation will be done using
UP/DOWN buttons. Once the last screen is reached, pressing down button will result in displaying the first page
again; similarly if up is pressed when the first screen is displayed the last page will be shown.
None of the navigation keys is included in the digital inputs to be diagnosed.
A high level representation on how this should be implemented is presented in Figure 9.

7.3.2.5. Configuration
The Vision cluster should provide a way to configure a specific set of parameters during the manufacturing
process at Bluebird facility.
The configuration of the cluster will be accomplished using the cluster user interface (i.e. stalk switches and
DID). Access to the Configuration option is protected and requires the user to provide the access code via the
“Password” option to enable it.
The configuration items that will be displayed in the configuration menu are described in Table 12.
It is necessary to execute an ignition cycle (OFF/ON), after revising desired parameters, for EE parameter
changes to take effect.
